VALVE FOR WASH-BASINS.

SPECIFICATION forming part of Letters Patent No. 439,818, dated November 4, 1890.

Application filed July 29,1890. Serial No.360,279. (No model.)

T0 at whom, it may concern.-

Be it known that I, J AMES WHITE HALE, of Newburyport, in the county of Essex and State of Massachusetts, have invented new and useful Improvements in Valve Mechanisms for Wash-Basins, of which the following is a specification;

This invention relates to an improved valve mechanism which does away with the ordinary loose plug and chain and leaves the bowl perfectly clear and free from all devices of that character with the exception of a valve or stopper, which is operated by a button on the top or table portion of the basin, the mechanism intermediate with said button and valve being entirely out of sight.

The nature of the invention is fully described below, and illustrated in the accompanying drawings, in which Figure 1 is a vertical section of a portion of a basin or bowl provided with my improved mechanism, which is shown in elevation and in the position assumed when the valve is raised so as to allow the water to pass down from the bowl into the waste-pipe. Fig. 2 is a detail of the mechanism, with the bowl and the rod L removed, partly in plan and partly in horizontal section on line as, Fig. 1, the position being that assumed when the valve is half open. Fig. 3 is an enlarged vertical section of the upper portion of the tubular valvestem, the valve being shown in elevation. Fig. 4 is a view partly in vertical section and partly in elevation, portions of the bowl and rod L being broken out, the valve being open.

Fig. 5 is a vertical section taken through the waste-pipe, with the tubular valve-stem in elevation and turned ninety degrees and nut D, which sets against the under side of the bowl, and the internally-threaded ring D, which sets against the upper side of the bowl flush with its surface. A suitable washer d may be interposed between the nut D and the bowl. The waste-pipe is provided with opposite openings O' in its sides next the overflow-passage A. (See Figs. 1, 4, and 6.)

E is a sliding pipe or tubular valve-stem fitting in and sliding vertically in the wastepipe 0, being prevented from rotation by the screw e, which extends through the wastepipe into the vertical slot E, Fig. 5, in the valve-stem. This valve-stem is cut away at its upper end, as shown, for a distance about equal to the width of the overflow-passage A added to the thickness of the wall of the bowl, leaving merely two integral posts E, which support a disk or head F, to which is secured the valve or stopper F, of suificient diameter to overlap the edges of and hence close the hole a in the bowl, and provided on its under side with a suitable washer f. When this valve-stem is raised, as in Figs. 1 and 4, the tubular portion closes the openings 0 in the waste-pipe, and the valve F is lifted, so that the waste-pipe is accessible to the water in the bowl, but not to any in the overflow-passage A. When the valve-stem is down, as in Fig. 6, the cut-away portion next the posts E is coincident with the openings C, and the valve F is down and closed, so that the waterin the bowl cannot flow into the waste-pipe, but the waste-pipe is open to the overflow-passage.

The valve-stem is raised and lowered, and hence the valve opened and closed and the overflow closed and opened from the top or table portion B of the bowl, by the following mechanism: The tubular valve-stem is provided with a horizontal slot g, by means of which it is engaged by a lever H, integral with and extending at right angles from a rocking shaft H, having bearings in a tubular plug 1, externally threaded and screwedinto an opening in the box or hollow extension 0, integral with the waste-pipe C and extend ing out one side thereof and constituting a housing for the shaft and lever H H. A portion near the outer end of this shaft is squared, Fig. 5, to receive the end J of the connecting-rod J. A flange h on the shaft H, Fig. 2, and a suitable nut h serve to keep the L". A nut Zserves to hold the rod L and bar K relativelyin the desired position. A guide tube or thirnble Nis set into the table B and the lifting-rod L extending through it. The button rests on the upper end thereof. The thimble is held in place by a nut n beneath the table and an integral flange N above it.

As will readily be seen, raising the button L lifts the rod L, bar K, and outer end of the rod J, rotating the shaft H and lowering the free end of the lever H, which, engaging the tubular valve-stem E by means of the slot g, pulls it down, and hence closes the valve F, while lowering the button L reverses the operation. As above mentioned, the operation of closing the valve opens the outlet to the overflow, while opening the valve closes said outlet.

In order that the valve-stem may be removed from the waste-pipe a vertical slot g connects the slot 9 with the lower end of the stem, so that by turning said stem ninety degrees (having first loosened the screw 6) it can be slipped out, as shown in Fig. 5.

The bar K may be disengaged from the rod J by swinging it down, as shown in Fig 2, thus bringing the flat button in line With the slot J.

The valve-stein E is stopped in its downward motion by the valve F striking on the ring D and in its upward motion by the button L striking the guide tube or thimble N.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

The combination of the waste-pipe 0, provided with the openings 0 and hollow extension 0, the tubular valve-stem E, provided with the posts E and valve F, and slotted at g, the lever and shaft H H, tubular plug I, connecting-rod J, slotted at J", bar K, provided with the button K, actuating-rod L, and button L, substantially as specified.
